Cha Tae Hyun accepted an interview with SBS Late Night TV Entertainment. During the interview, he suddenly raised a question to the Running Man director. He asked, " What do you think about Kim Jong Kook starring in two days one night, while I appear in Running Man? This revealed Cha Tae Hyun desire to join the Running Man team.

He stated that if one on one trade in is a little difficult, they can add in Lee Kwang Soo. If the team does not coordinate well, we can give the Running Man team Kim Jong-Min. It was a joke that Cha Tae Hyun used Lee Kwang Soo as a "free gift" to the other party. What do you think if both of them (Kim Jong Kook and Cha Tae Hyun) really exchange Variety show?
